*
* For connectionless protocols, just pass the socket into the kernel via
* nfssvc().
* For connection based sockets, loop doing accepts. When you get a new
* socket from accept, pass the msgsock into the kernel via nfssvc().
* The arguments are:
* -c - support iso cltp clients
* -r - reregister with portmapper
* -t - support tcp nfs clients
* -u - support udp nfs clients
* followed by "n" which is the number of nfsd threads to create
